Question

if a scale map is 1 cm: 15 Km. find the actual distance corresponding to the scale map. 13) 2.5 cm 14) 0.2 cm 15) 15 cm 16) 4.6 cm

Answer 1

All you gotta do is multiply the cm by 15,
For 13) you'd do $2.5*15$
14) $0.2*15$ 
15) $15*15$
then for 16) $4.6*15$

Answer 2

Let

x-------> distance in the map in cm

y-------> actual distance in Km

we know that

$Scale\ Map=\frac{x}{y} \\ \\ Scale\ Map=\frac{1}{15}\frac{cm}{Km}$

so

$\frac{x}{y}=\frac{1}{15}$

$y=15x$ --------> equation $1$

Part 13) find the actual distance corresponding to the scale map $2.5\ cm$

In this problem we have

$x=2.5\ cm$

Substitute the value of x in the equation  $1$ to find the actual distance

$y=15*2.5=37.5\ Km$

therefore

the answer part 13) is

the actual distance is $37.5\ Km$

Part 14) find the actual distance corresponding to the scale map $0.2\ cm$

In this problem we have

$x=0.2\ cm$

Substitute the value of x in the equation  $1$ to find the actual distance

$y=15*0.2=3\ Km$

therefore

the answer part 14) is

the actual distance is $3\ Km$

Part 15) find the actual distance corresponding to the scale map $15\ cm$

In this problem we have

$x=15\ cm$

Substitute the value of x in the equation  $1$ to find the actual distance

$y=15*15=225\ Km$

therefore

the answer part 15) is

the actual distance is $225\ Km$

Part 16) find the actual distance corresponding to the scale map $4.6\ cm$

In this problem we have

$x=4.6\ cm$

Substitute the value of x in the equation  $1$ to find the actual distance

$y=15*4.6=69\ Km$

therefore

the answer part 16

the actual distance is $69\ Km$
